Anyone have any battery life tips. Still don't seem to be getting amazing battery life on the 920.
BTW, how much is your battery able to last on an average?
Charge your phone to 100%, and then don't use it too much (NO GAMING AND BROWSING FOR LONG TIMES) and drain the battery completely until the phone switches off. Repeat the cycle for somewhere between 3 and 5 times.
The trick is to not charge it while it doesn't drop to sub-10% levels (unless you really have to).
Takes a hell lot of control, but hey, I now get about 15 to 13 hours with Mobile Data (2G) always on, WiFi (about 3 hours daily), downloads (about 100MB a day), gaming for about 30 mins daily.
Earlier it used to last just about 9 to 10 hours.
Apart from it: (Assuming you don't use the phone for office purposes)
1. Try using WiFi instead of Mobile Data.
2. Turning off Double Tap To Wake does help.
3. Keep 'location' off when not needed.
4. Try closing down some Background Tasks (by swiping to the right on the Settings page, the first option.)
5. Set the brightness to automatically adjust itself.
6. Set your email to sync less often (or better still, use to "Sync as email arrives" option for hotmail (outlook, live) accounts.
7. Set the lock screen to timeout at 1min.
